IMPROVED ICE-PITCHER.

TO ALL WHM IT MAY CONGERN:

Be it known that I, GEORGE H. BECHTEL, of the city and county of Philadelphia, and State of Pennsylvania, have invented certain new and useful improvements in Ice or Double-Jaoketed Pitchers; and I do hereby declare the following to be a full, clear, and exact description of the same, reference heilig had to the accompanying drawings, making a part of this specification, in which- Figure 1 represents a perspective View; and

Figure 2 represents a vertical section through the pitcher, showing its inter-lor construction.

In double pitchers as at present constructed there is a soldered or other joint at or near the bottom of inner shell or jacket, w-hich, by the ordinary expansion and contractionof 4the metal under the varied temperatures of itscontents, will open and leak; and beside this, the dropping into it of ice strains or this joint, so that from this cause the liability of any joint in that locality to open is much increased. I am aware that the bottom of the inner jacket has been made concave so as to raise the joint, and cause it to unite with the sides in aline more nearly tangential to the sides, but this does not remove the joint from the iniluence of the ice or water, and is as liable to open as if it were at the corner or extreme lower end. I propose to remedy this defect by dispensing entirely with a joint in the inner jacket below the lline of water or ice, and consequently there cannot be any opening or leakage in the inner jacket from these causes. Andi my invention consists in making the inner jacket of the pitcher in one piece, and without a joint, and uniting it to the outer jacket at or near its top, where it will be beyond the casualties incident -to the hitherto-practised plans of making these double pitchers.

The form of ice pitchers as at present constructed is generally pyramidal, and always, so far as I know, of greater area in the under than in the upper portion thereof. I reverse this, and make my pitcher of an egg form, with the larger end and area uppermost, which admits of a larger opening anderen. for the introduction of the ice, and prevents it 'from dropping heavily on the bottom of the pitcher when introduced in large pieces, as should he done, as it is thus more enduring or less liable to rapid melting away. By this shape or form the lid is more of a dome form, and makes a dead-air space under it, which resists the conduction of heat and cold, and more perfectly insulates the interior from thetempe'rature of the exterior of the pitcher. It furnishes, besides, a chamber for the ice to protrude into when it projects above the top of the pitcher, and allows the lid to shut down close upon its seat, notwithstanding this projection of the ice. And my invention in this particn'lar consists in making double pitchers ot' an inverted egg shape or form, so that the top, bottom, and sides shall all he arched or curved, and without angular joint, and with greater area above than below its centre part, and with a dome or inverted howl-shaped lid to form an air-chamber above the seat of the lid.

To enable others to make and use my invention, I will proceed to describe the same with reference to the drawings. l i. i

I take any of the metalsor alloys of metals that are textile enough to he spun up into the proper form, and of the finer or cheaper qualities, as may be preferred. The outer and inner jackets a b may both be spun up into the form as shown in the drawings, and united at'c, which is the seat for the lid. It is all-important that the innerV jacket'b should he spun up and made in one piece, so as to avoid any and all joints in it, which are so liable to'op'en and leak; and though I prefer to spin up the outer jacket a in one piece also, yet'this is not so necessary, as it is not so subject to the causes that produce Vleaks in the inner jacket; and the outer jacket may lhave a joint, Whichvcould he covered by thc base [l where it is united to the body of the pitcher, but, asV before stated, VI prefer to spin it up in one piece. The form of the exterior and interior of the pitcher is such thatit will he of greater diameter and area at its upper than at its under portion, and for this purpose I prefer and select the inverted egg form or shape, that is, the form of an egg when standing on its 'apex or small end, as I thus get more ice space in proportion to Water space, and greater facility for the insertion of the ice in larger pieces, in which condition it wastes less rapidly, and less liability of injury of the inner jacket hy the dropping in of heavy pieces of ice into it. The lid e as well as the body of thepitcher is double, with dead-air space between as a non-conductor of heat. This lid is of a dome form, so that when down on its seat there is a large chamber,f, under it, int-o which the ice may protrude when it is higher than the top of the body of the pitcher. The lid is hinged to the body at g. The spout h is put on in the ordinary way, and the opening from the interior of the pitcher into the interior of the spout is controlled by a hing-ed valve, i, that closes said opening when the pitcher stands erect, and opens by the pressure of the Water when it is tipped, as in the act of pouring7 out Water. -The pitcher may be ornamented in a high degree, or plain, as suits the taste ofthe maker or user, and may be made of the more prec.ous as Well as of the baser metals, or alloys of them. The lid, as shown in the drawing, is more liat than a section of an egg(\vl1icl1 form I prefer) would be; but this I propose to round up into a dome or inverted bowl form, so as to more clearly resemble the egg forni.

Having thus fully described lny invention, what I cla-inl is In double or ice pitchers the making of the inner shell or jacket in one piece and without a joint, so as' to prevent its liability'to leak, substantially as described.

Ialso claim, in combination with doublc-jaclieted or ice pitchers, the making of the inner area thereof greater above its central portion than below that point, when this is attained by curved or arched top, bottom, and sides, and without angular joints, as and for thepu'rpose described.
